Digital model of shovel work process

The discussion focuses on improving efficiency of front-acting shovels by means of coordination of functions of main propelling machinery during excavation. The feature of the main propelling machinery (hoisting and crowding gears) is the kinematic connection between their shafts as the members of the mechanisms and components of the shovel equipment (lever, boom point sheave, bucket and ladle hanger) generate an integrated kinematic chain. The kinematic chain is included in the transversing gear of the main propelling machinery together with the leverage mechanism. The joint coordinates of the leverage mechanism (coordinates of the top cutting edge of the bucket) define position of all movable members of the main propelling machinery, leverage mechanism and gearing shafts. The kinematics and forces of the leverage mechanism are analyzed. The constructed mathematical model of the excavation process determines the bucket position (upper cutting edge) in the work zone of the shovel. Based on the computational experiment, the digital model of excavation by shovels is developed. The studies can be used to create an automated control for the main propelling machinery both during actual excavation of rocks and when performing haulage operations in the shoveling cycle.
